S32k328 flashing

[leo_Z]

HI everyone,

we have one hardware, and there is already one image is present, and we are trying to flash the base image(empty image with for loop) which is created by Design studio.

we can't use design studio to flash, we have one flashing script which is verified, after we flash the very basic image , we can't flash again the any image even the older image, we are getting some error on gdb , could any explain me what is happing here, and to solve this

Hi @leo_Z,

From the short log I see the debugger reports that the application core detected a fault exception.

Do you have any other debuggers?

Have you tried both SWD and JTAG protocols?

Can you just attach the debugger to the MCU without programming it?

Can you debug the code right from the reset handler?

Try keeing the MCU in reset as described here:
